以耐高温光敏树脂为材料,采用光固化快速成型方法制作具有所需形状的注射模型芯,根据光固化成型和树脂材料性能的特点,从光固化型芯的翘曲变形、浇口设计、微结构设计、随形冷却水道设计方面对光固化型芯设计和制造中的关键技术进行了研究,以改善光固化型芯的缺陷,实现快速开发出高精度、长使用寿命、实用化的光固化型芯的研究目标。
Injection mould cores with required shape can be made of high temperature resis- tant photosensitive resin by the means of light-cured rapid forming. Study was made on the key technology of light-cured core design and .manufacture from aspects of core warpage and design of gate, micro-structure and conformal cooling channels and on the basis of characteristics of light-cured moulding and resin material properties, in order to decrease the defect and rapidly develop practical high precision and long life light-cured cores.
